I've always been a bit of a self-doubter, I think a lot of actors are. I still am.

You have to look at your blessings, don't you? With Thrones, I have to realize that, whatever happens, and for all the stress and the pressure that goes with it, it's been an extraordinary journey and I know I'll look back later in my life and think, 'That was crazy, that was amazing.' It's something that very, very few people experience, and I love that.

It's very difficult to say anything in Icelandic. I can say "takk," which means "thank you." That's about all I learned.

It's a nightmare if you're working with someone you don't get on with, especially if you have to be in love with them.

You don't want to seem too eager, too romantic - otherwise, it just looks a bit try-hard. But I do think that a first date should be intimate. So I'd choose a nice dinner somewhere cozy, not too crowded, with good wine.

I'm very much a "that's so obvious, I must not mention it" kind of guy.

Each project changes you a bit.
